To @ZZ whom t may Concern:

Be it known that I, HUGO HAEFNER, of Linden, Union county, New Jersey, have invented an Improved Filter, of which the following is n speeiiien-tion.

rllhis invention relates io :t iilter for water and other liquids which is so eonstrneted that the liquid is divided into n sprnj.,end is thus thrown ogn-inst the pereolm'ing-disk.

The invention Consists in the various feotures of iinlnovenieni more fully pointed ont in the Claims.

In the accompanying drawings, Figure l is a side view of niy improved filter. Fig. 2 is i5 :in outerview et' one oit' the disks o. 3 is a longitudinal central section ot' the filter on line a?, Fig. i. Fig. -i is on inner view of one of the disks o. on line y 11j, Fig.' i.

The letters d ci represent n pnir oi" disks, between the rims of which i Washer, b, is interposed, and ivhieh nre clamped together by binding-serews e. Eneh of the disks o has on outxmrdly-projeeling screw-threaded socket, d, that reeoives n. nut, d', holding a twouvztv oook, e. The plugs f of these cooks are united by nv pi voted freine, g g, having handle g', by ineens oi which both eoeks ning: be sininltaneousljrY operated.

The disks d :ire centrally perforated Within their sockets for the ingress and egress of the liquid. At its inner side the bodv of eneh disk is pftrtinllv ont mmv, so ns to lonve a series oit' rndinling ribs, d.

Fig. 5 is :i eross-soelion These ribs join n-t their outer ends nu annular oi et o?, oi the disk. At their inner ends they loin n sinnll I disk, o, placed neross the eentrnl opening.

ltuill thus be seen that the inner i'nee of eneh disk is subdivided into n series of seeio toushaped envii'ies, di. Eneli of these ezivh ties communicates with the central opening oi' the disk by n small lateral peri'mnlion, d,

/l is n sheet of felt or other pereolnlor chnnped between the di: s o o. This per eoloi'or, tilted upon olli s o?, will he held between the ribs d oi' the disks, :ind thus those paris oi the pereolntorwhich extend across the envities o" will be lfree lo the neeess of the liquid to he iiltered.

One of the cook" e connects et e with the unter-supply and .at ei With the Waste. The

other oook e connects at e:g also with the Woter-supply and at el with the house-service.

The opera-tion of the deviee is as follows: One turn of handle g will open the inlet-port e and the service-supply port el, and will elose the ports e3 e3. In this position the water will pass through the central opening ot' one disk, d., (lowerxnost disk, Fig. 3,) and strike its inner central small disk, of. This Will deflect. the water, and will esuseI it to rush through the lateral perforations 60" into the cavities a4. Thus the Water is spread across the entire surface of the pereolator h. After having passed through the pereolator the filtered writer will eolleet in the eiwit-ies di of the opposite disk, and, passing through the lateral perforntions of and the cook, 1vill be Conducted to the service-port el. Of eourse sediment will in time settle upon the fate-e of the pereolator which is opposite the inletport e. To Wash this sediment off, the plugs faire turned to open ports es 2n-nd close ports e e4. The course of the ivnter will now be reversed, and the Water will Wash the sedinient into the wsstepipe.

That I elniin is- .l. The combination of disks o, hnvin g ribs d and onvities a4 on their inner ieee, with an interposed pereolntor, 7i, xamd with inlet and disehorge pipes connected to the disks, substantially ns specified.

2. The Combination of disks d, having radial ribs d and cavities o4 on their inner foce, with the disks of", placed beek of the inlet and discharge openings of the disks d, nnd with perforations a, Connecting such openings with the cavities o," and with percolnl'or 7i, and with inlet and discharge pipes, substantially as speeilied.

I). The eonibinntiou oi' disks @,hnving disks u, ribs a', perforations d, and sockets d, with eoeks e, reeeived by said sockets and having plugs f, and with the pivoted freine g g, engaging said plugs, and with the pereolator h, Washer b, and binding-screws e, substantially as specified.
